The power converter was a 65 amp three stage converter. I was surprised about the 65 amp rating with how big the RV is. Fifth wheel with two slides, two AC units, two TVs, etc. Anyhow, they had a converter on amazon that was the same model and series, but was 75 amps (it was the exact same physical size). It arrived today, I plugged it in and saw 13.6 volt output (old one was zero). Unplugged it and wired it in, mounted it, and all seems well with the RV now.
The only fatality that I can figure out from the shore power jack being wired wrong is one of the TVs does not work. 115vac at the outlet, but does not come on. Smaller LED TV...not sure if they have fuses inside, but it would probably be too cheap to replace the whole TV to make it worth disassembling and trying to figure out if it can be fixed.
She had the battery on a charger for 9 or 10 hours set at 10 amps. It read 11.8 volts when I got there...so going to need a battery eventually.
Thanks again,
